Perimeter Of Rectangle = 2(L+B)

70 = 2 × (L + 15)

= 30 + 2L

= 70 - 30

Answer 2

Answer:

Let the length of the sheet be l cm.

Breadth = 15 cm

A.T.P,

2( length + breadth ) = 70

2 ( l + 15) = 70

2l + 30 = 70

2l = 70 - 30

l = 40/2

l = 20 cm

The area of the rectangular sheet = length × breadth

= 20 × 15

= 300 sq.cm
