Question

The length of a rectangle is 160% of its
breadth. If the breadth of the rectangle is
50 cm, find
(a) the length of the rectangle and
(b) the perimeter of the rectangle.​

Answer 1

Answer:

30 cm

Step-by-step explanation:

Perimeter of rectangle = 160 cm.

Length = 50 cm.

2(L+B) = 160

2(50 + B ) = 160

50 + B = 80

B = 80 - 50 = 30 cm.

Breadth of rectangle = 30 cm.

Answer 2

Answer:

1. 160% of 50 is 80.
2. Then, the length is 80 and the breadth is 50.
3. Perimeter of the rectangle = 2( l + b )
4. So, 2( 80+50 ) = 2(130) = 260cmsq.
5. Length is 80 & perimeter is 260
