Question

erimetre of a rectangle is 20m, its length 8m, find area *

Answer 1

Answer:

perimeter is 2l+2b

l=8,2l=16

so,20+16=4

so breadth=2

area is l×b

area is 16m^2

Answer 2

Step-by-step explanation:

To Find the area we have to find the Breadth of Rectangle .

Perimeter of Rectangle= 2(L +B)

20 m = 2 (8m +B)

20m = 16m + 2B

20m -16 m = 2B

4m ÷ 2 =B

2m = B

Now Area = L * B

= 8m * 2m

= 16m²
