Question

Rahul wants to put lace all along the edges of a curtain. How much lace will she need if
the length of the curtain is 75 cm and the breadth is 50 cm?​

Answer 1

Given,

Length of the curtain = 75 cm

Breadth of the curtain = 50 cm

To find,

The length of the required lace.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

From the given dimensions we can assume that the shape of the curtain is a rectangle and we need to calculate the perimeter of the rectangular curtain in order to find the length of the required lace.

length of the required lace = perimeter of the curtain = 2 × (75+50) = 2× 125 = 250 cm

(This length of lace will be enough to put laces along all the edges of the curtain.)

Hence, the length of the required lace is 250cm.
