Question

Find the area of a rectangle with length (3x+2) units with width ( 4x+10 ) units​

Answer 1

Area of rectangle = Length × Width

• Length - (3x+2)
• Width - (4x+10)

Area of rectangle = (3x+2) × (4x+10)

Area of rectangle = 3x(4x+10) + 2(4x+10)

Area of rectangle = 12x² + 30x + 8x + 20

Area of rectangle = 12x² + 38x + 20

Hence , the area of rectangle is 12x² + 38x + 20 units

Answer 2

Explanation:

Area of rectangle = length * width

= (3x + 2)(4x + 10)

= 3x *(4x + 10) + 2*(4x + 10)

= 3x *4x + 3x *10 + 2*4x + 2*10

= 12x² + 30x + 8x + 20 {Combine like terms}

= 12x² + 38x + 20
