Question

Write and simplify an expression to represent the area. Then determine the area when x = 3

Answer 1

5*8 = 40

Explanation:

2(3) -1 = 5

3 +5 = 8

area = 5*8 = 40

Answer 2

formula-Area=l×b

Explanation:

Length (l)=2x-1

Breadth(b)=x+5

We know that,

Area(A)=l×b

=(2x-1)×(x+1)

=(2×3-1)×(3+1)

=5×4

=20cm*2*
