Question

The length of a rectangle is four times it’s width. If the perimeter of the rectangle is 50 cm, find it’s length and width

Answer 1

Answer:

Let us assume that the width is X m. Then the length is 4 times the width. So length will become 4 X.

Perimeter is the sum of all sides, which equals to X + 4X + X + 4 X, equals to 10 X.

10 X equals to 50 m, so 1 X becomes 5. So the width is 5 m.

Area is length times width.

Length is 4 times width, which is 20 m.

Area becomes 20 times 5, which equals to 100 square meters

Answer 2

Answer:

Let the length of the rectangle be 4x cm

and breadth be x cm

By the problem,

2(4x+x)=50

》8x+2x=50

》10x=50

》x=50÷10

=5

Length =4x

=4×5

=20cm

Breadth=x

=5 cm
