Question

1. The perimeter of a rectangular plot of land is 80 m and its breadth is
16 m. Find the length and area of the plot.​

Answer 1

Answer:

perimeter of rectangle=2(l+b)

=2(l+16)=80m

l+16=80/2

l+16=40

l=40-16

length=24m

area=l*b

24*16=384m

therefore length=16m

area=384m

Answer 2

Answer:

p=80

b=16

l=?

perimeter of rectangle= 80

= 2( l + b ) = 80

2 ( l + 16 ) = 80

l + 16 = 80/2

l + 16 = 40

l = 40 - 16

l = 24

area of rectangle = l × b

= 24 × 16

A = 384m

so the length of rec. is 24m and area of rac. is 384
