Question

the length of a rectangle is 20cm more than its breadth If the perimeter is 100cm find the dimension of the rectangle​

Answer 1

Answer:

length = 35cm

breadth = 15cm

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

length = x + 20

breadth = x

100 = 2 ( x + 20 + x)

100 = 2 (2x + 20)

50 = 2x + 20

2x = 30

x = 15

Length = x + 20 = 15 + 20 = 35 cm

Breadth = x = 15 cm
