☥ Which pair of expressions represents the area of the rectangle?
☐ 2(x + 1) + 2 (4) and 2x +9
☐ 2(x + 1) +2 (4) and 2x + 10
☐ 4(x + 1) and 4x + 1
☑ 4(x + 1) and 4x + 4
☪ 
- Length of a rectangle ( L ) = 4
- Breadth of a rectangle ( B ) = x + 1
☪ 
- Pair of expressions which represents the area of the given rectangle
☪ 
❀ 
↦ 
↦ 
Also , In 4 ( x + 1 ) , if we distribute 4 through the parentheses , it would be 4*x + 4*1 =
.
Hence , the right answer is of last option { i.e 4 ( x + 1 ) and 4x + 4 } .
And we're done !
Hope I helped!!
