Question

The length of a rectangle is 7 cm more than twice the width. The perimeter is 86 cm. Find
the dimensions of the rectangle.

Answer 1

Answer:

Length is 12 cm and breadth is 31 cm

Step-by-step explanation:

Breadth = x cm and Length = 2x + 7

P = 2(l + b)

86 = 2(2x + 7 + x)

86/2 = 3x + 7

43 = 3x + 7

43 - 7 = 3x

36 = 3x

12 = x

x = 12 cm

2x + 7 = 24 + 7 = 31 cm

Answer 2

Step-by-step explanation:

length = 2x+7

breadth = x

perimeter =2(l+b)

86=2(2x+7+x)

43=3x+7

36=3x

12=x

breadth 12 and length 31
