Question

The length of a rectangle is 10 m more than its breadth. If the perimeter of recantangle is 80 m. Find the dimensions of the rectangle.

Answer 1

Answer:

length = 25 m

breadth = 15 m

Step-by-step explanation:

Let the breadth be x

then, the length is x+10

perimeter=80 m

perimeter of a rectangle = 2(l+b)

80 = 2(x+10+x)

80 = 2(2x+10)

80 = 4x+20

4x = 80-20

4x = 60

x = 60/4

x = 15

length= x+10

= 15+10

= 25 m

breadth= x

= 15m

Answer 2

Answer:

2×10+80m

2×90m

180m

so, the dimension of the rectangle is 180
