Question

Q1. The perimeter of the square ABCD is twice the perimeter of the triangle PQR. If the sides of the triangle are 21cm, 29cm, and 34 cm, find the length of each side of the square.​

Answer 1

Answer:

Let the Perimeter of the Triangle be x

Then, Perimeter of Square= 2x

Step-by-step explanation:

Given, Sides of the Triangle=

21cm, 29cm and 34cm

So, x= (21+29+34)cm

x= 84cm.

Therefore, Perimeter of Square= 2x

=(2×84)cm

=168cm.

Now, as we know,

Perimeter of Square=

$4 \times side$

So, Side=

$\frac{perimeter}{4}$

Side=

$\frac{168}{4}$

Side= 42cm.

So, the length of each side of the Square is 42cm.
