Question

14. 34 15. The area of a square is 25 m2, find its perimeter. The length and breadth of a rectangle are 12 cm and 10 cm respectively. Find the perimeter and area of the rectangle. 3​

Answer 1

Answer:

area of square=25

L^2=25

L=√25

L=5

now,

perimeter of square=4L

=20

again,

length of rectangle=12cm

breadth of rectangle=10cm

perimeter of rectangle=2(L+B)

=2(12+10)

=44 cm

area of rectangle=L×B

=12×10

=120cm^2

Answer 2

Answer:

14. For square,

Area(a)= 25 m²

Therefore, Lenght of one side(l)= √a

= √25 m²

= 5 m

∴ Perimeter= (4×l) units

= (4×5) m

= 20 m(Ans)

15. For rectangle,

Lenght(l)= 12 cm

Breadth(b)= 10 cm

∴ Perimeter= 2(l+b)

= 2(12 + 10) cm

= (2 × 22)cm

= 44 cm(Ans)

∴ Area= l×b

=(12 × 10)cm²

=120 cm²(Ans)
