Answer 1

Answer:

Question 1

Area of Rectangle = L × B

a) L = 7 cm

B = 4 cm

Area of Rectangle = 7 cm × 4 cm

= 28 cm²

b) L = 21 m

B = 2 m

Area of Rectangle = 21 m × 2 m

= 42 m²

Question 2

Area of Square = S × S

a) S = 11 cm

Area of Square = 11 cm × 11 cm

= 121 cm²

Question 3

Given,

Length of cloth = 2 m

Breadth of cloth = 1 m 25 cm

Conversion

1 m = 100 cm

1 cm = 1/100 m

25 cm = 25/100 m

= 0.25 m

1 m + 0.25 m

= 1.25 m

We can observe that the sides of the shape are not equal. Hence, we can be sure that this is a rectangle, and NOT a square

Area of Rectangle

Area of Rectangle = L × B

L = 2 m

B = 1.25 m

Area of Rectangle = 2 m × 1.25 m

= 2.5 m²

Question 4

Area of Rectangle = L × B

L = 50 m

B = B

Area = 300 m²

=50 m × B = 300 m²

(Transversing of 50 m to RHS)

B = 300m² / 50 m

B = 6 m
