Question

Find the area of a rectangle if its length is 38cm and perimeter is 120 cm.

Answer 1

Answer:

836 sq.cm

Step-by-step explanation:

P=2(L+B)

B=(P/2)-L

B=(120CM/2)-38

B=60CM-38

B=22CM

Area = L*B

Area = 22cm*38cm

        =836sq.cm

Answer 2

Step-by-step explanation:

Given, length = 38cm

let breadth be m.

Perimeter = 120cm

2(l+b) = 120cm

2(38+m) =120

76 +2m = 120

2m=120- 76

m = 44÷2

m= 22

So breadth = m= 22cm

and length= 38cm

Area = l×b

22×38

= 836cm^2

hope it helps!
