Question

The length of a rectangle is 11 cm more than it’s breath . If the area of the rectangle is 350 cm2, what is the length and breath of the rectangle?

Answer 1

Answer:

Let the breadth of the rectangle be 'b'

∴ The length = 11 + b

Area of the rectangle = 350cm²

Area of rectangle = length x breadth

350 cm² =  11 + b × b

350 cm² = 11 + b²

b² = 350 - 11

b² = 339

b = √339

∴ The breadth, b of the rectangle = √399 cm

Length of the rectangle = 11 + b

= 11 + √399 cm

∴ The length and breadth of the rectangle is 11 + √399 cm and √399 cm

(You can simplify 11 + √399 = 30.9749843554 and √399 = 19.9749843554 )
