Is the length of the rectangle is increased by 20\% and the breadth is reduced by 20\% What will be the effect on its area?

Ans. And so both the effects need to be taken together. An increase of 20\% in length would increase the area by 20percent.

Increase in the area of the rectangle is 44\%. After 20\% increase in Length and Breadth, (120/100*L)*(120/100*B) = 144/100*LB . Hence, increase in area = 144/100*LB – LB = 44/100*LB = 44\% Ans.

What is the increase in the perimeter of a rectangle?

The perimeter always increases if we increase the area of square or rectangle.

What is the increase in the area of rectangle if one of its sides increased by 25\%?

New Area =(6/5x × 6/5y)m2=(36/25xy)m2. Hence, Increase \% =(11/25xy × 1/xy × 100)\%= 44\%.

When perimeter of square increases the area of Square always increases?

As perimeter increases that means the the side of the figure increases. And area depends on the sides of figure so its a true sentence!!

When perimeter of a square increases the area of Square always increase True or false?

When perimeter of a square increases, the area of square always increases.

What is the increase in area when the sides of a rectangle are increased in length by 100 \%? *?

Since sides are increased by 100 \% therefore increased sides would be 2X, 2Y respectively. Increase in Area in \% = (4XY/XY) × 100 = 400 \% Ans.

What is the percentage increase in length and breadth of rectangle?

The length and breadth of a rectangle are increased by 20\% and 40\% respectively. What is the percentage increase in its area? If length and breadth of a rectangle are increased by 15\% and 20\% respectively then what will be the percentage, increase in area? Remember that area, A, equals L * W (or length times width). (W will be “breadth”).

What is the percentage change in perimeter when length is increased?

Originally Answered: If length of rectangle is increased by 20\% and breadth by 10\%, what is the percentage change in the perimeter? New length = L + 0.2L where L is the original length. New breadth = B + 0.1B where B is thr original breadth. = LB (1.2) (1.1) = 1.32 LB where LB is the old area. That is 32\% increase in area.

What is the area of the rectangle if the length is 20\%?

What is the percentage increase in area from 15\% to 20\%?

If length and breadth of a rectangle are increased by 15\% and 20\% respectively then what will be the percentage, increase in area? Remember that area, A, equals L * W (or length times width). (W will be “breadth”). where x is the percentage increase. So a 15\% increase in length and a 20\% increase in breadth will result in a 38\% increase in area.
