​

Answer 1

Answer:

Step-by-step explanation:

The area of a rectangle is (x2 + 2x - 15) square units. If the length is (x + 5) units, find its breadth.

Answer 2

Question:

Area of a rectangle= (x²+2x-15) unit²

It's Length= (x+5) units

Find breadth.

Solution:

Area= length (l)×breadth(b)

x²+2x-15=(x+5)b

x²+5x-3x-15=(x+5)b

x(x+5)-3(x+5)=(x+5)b

(x-3)(x+5)=(x+5)b

b=(x-3)

Answer:

Breadth= (x-3) units.
