Question

Happy RM day to all plz solve this fast with full explanation​

Answer 1

$area = {s}^{2}$

$perimter = 4 \times s$

(I) 60cm. 3600cm². 240cm

(Ii) 8cm. 64cm². 32cm

iii) 35cm. 1225cm². 100cm

Answer 2

Here's your answer:

Using the Formula of Square here ⤵️

*Things to remember :-

Area = (side)²

Perimeter = 4 x side

*NOTE : Here, a = side

(i) Given: a = 60cm

To find : Area & Perimeter

Area = a²

=> (60cm)²

=> 3600cm²

Perimeter = 4a

=> 4*60

=> 240cm

Hence, Area = 3600cm² & Perimeter = 240cm

(ii) Given: Area = 64m²

To find: a & Perimeter

=>Area = a²

=> 64m² = a² (squaring both the side) we get,

=> (8m)² = (a)²

=> 8m = a

therefore, a = 8m

Perimeter = 4a

=> 4*8

=> 32m

Hence, a = 8m & perimeter = 32m

(iii) Given: Perimeter = 100mm

To find: a & Area

=> Perimeter = 4a

=> 100mm = 4a

=> 100/4 = a

=> 25 = a

therefore, a = 25

Area = a²

=> (25)²

=> 625mm²

Hence, a = 25mm & Area = 625mm²

I hope it will help you
