Question

find the area of rectangular whose perimeter 100 metter 20 metter bredth​

Answer 1

Step-by-step explanation:

if perimeter is 100

then 2l + 2b = 100

2X = 100-(2*20)

X = 60

therefore Length is 60

AREA = L*B

60*20

1200m square

Answer 2

Step-by-step explanation:

A = 2 (l + b)

100 = 2 ( l + 20 )

100÷2 = l +20

50 = l+ 20

50 - 20 = l

l = 30

Area = length × breadth

= 30 × 20

= 600 Sq
