*!* find the area and perimeter of the shapes below.

a: 15 in

b:210 cm

c: 21 yds

Step-by-step explanation:

a: to find the area of a triangle multiply the base and the height, then divide the result by two.

b: to find the area of a trapezoid, multiply the median ( the point where the opposite corners cross) and the height.

c: to find the area of a parallelogram, multiply the lenght and the height.

Hope this helps!

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
