Question

3. The perimeter of a square PQRS is twice the perimeter of a AABC of sides 13 cm, 12 cm and 5 cm
Find the area of the square.​

Answer 1

Answer:

given that triangle sides are 13,5,12cm perimeter of triangle-13+5+12

=30cm

perimeter of square=2(30)=60cm

for sides of square,

perimeter of square=4xside

60=4xside

side=15cm

area of square=15^2 =225cm square

Answer 2

Step-by-step explanation:

x = side of square

perimeter of ∆ABC

=5+12+13

=30

perimeter of square

=2×30

=> 4x =60

=> x= 60/4

=15

Area of square

=x²

=(15)²

=2²5
