Question

The area of a rectangle is 150 sq cm. If one of its sides is 10 cm, what is the length of its other side? Also find the perimeter of the rectangle​

Answer 1

Answer:

• Length of side = 15cm
• Perimeter of rectangle =50cm

Step-by-step explanation:

Given :-

• Area of rectangle = 150sq cm.
• breadth of rectangle =10cm
• Length of rectangle = x

To Find :-

• Length of rectangle.
• Perimeter of rectangle.

Formulas of ' Area and perimeter ' rectangle :-

• Area of rectangle = Length× Breadth
• Perimeter of rectangle = 2( length+ breadth)

Explanation :-

• Area of rectangle = Length× Breadth

150 = 10 × x

150 = 10x

x = 150/10

x = 15cm

so,

Length of rectangle = 15cm

so,

we have length of rectangle = 15cm

nd, breadth of rectangle = 10cm

• Perimeter of rectangle = 2( length+ breadth)

= 2(15+10)

= 2×25

= 50cm

so,

Perimeter of rectangle = 50cm

Answer 2

Step-by-step explanation:

Given,

Area of a rectangle = 150sq cm

Breadth of a rectangle = 10 cm

length of a rectangle = x

Area of a rectangle - length × breadth

150 = 10××

150 = 10 ×

x = 150/10

x = 15 cm

length of a rectangle = 15 cm .
