Question

The length of Rectangular field is 8m longer than its breadth.if the perimeter is 88m..find its area

Answer 1

Step-by-step explanation:

l = 8+b

perimeter = 88m

l+b= 88

8+b+b =88

8+2b=88

2b=80

b=40

l=40+8

=48

area = l*b

40*48= 1920

Answer 2

Let breadth be x

length be 8+x

Perimeter = 88m

ATP

2(l+b) = perimeter

= 2{(8+x)+x} =88

= 2(8+2x) =88

=16+2x =88

= 2x = 88-16

= x = 72/2

= x = 36

Length= 8+x

= (8+36)m

= 44m

Breadth= 36

Area =(l×b)

=(36×44)m^2

= 1584 m^2
