Question

Find the perimeter and area of the rectangle whose dimensions are

1) 8cm by 5cm
2) 3.5m by 2m

Answer 1

Answer:

1)26cmsq

2)11cmsq

Step-by-step explanation:

1)2 *(l+b)

=2*(8+5)

=2*13

=26cm

2)2*(3.5+2)

=2*5.5

=11cmsq

Answer 2

Answer:

(1) Area = 40 cm^2

Perimeter = 26 cm

(2)Area = 7m^2

Perimeter = 11m

Step-by-step explanation:

(1) length (l) = 8 cm

Breadth (b) = 5 cm

Area of rectangle = length × breadth

Area of rectangle = 8cm × 5cm

Area of rectangle = 40 cm^2

Perimeter of rectangle = 2(l+b)

Perimeter of rectangle=2(8+5) cm

Perimeter of rectangle=2×13 cm

Perimeter of rectangle=26 cm

(2) Length (l)=3.5 m

Breadth (b)=2m

Area of rectangle = length × breadth

Area of rectangle = 3.5 m × 2m

Area of rectangle = 7 m^2

Perimeter of rectangle = 2(l+b)

Perimeter of rectangle = 2(3.5+2) m

Perimeter of rectangle = 2 × 5.5 m

Perimeter of rectangle =11 m
