Help ASAP 4 The parallelogram shown below has an area of 21 units?.
7
b
8
Find the missing base.
b=
units

The missing base b is 3 units

Step-by-step explanation:

Let us solve the problem

In the given figure

∵ The given figure is a parallelogram

∵ The line of length 7 is perpendicular to the base that parallels to base b

∵ The base b has a height of 7 units

→ By using the formula of the area above

∵ A = b1 × h1

∵ b1 = b and h1 = 7 units

∵ The parallelogram has an area of 21 square units

∴ A = 21

→ Substitute the value of A and h in the rule of the area

∵ 21 = b × 7

∴ 21 = 7b

→ Divide both sides by 7

∴ 3 = b

∴ The missing base b is 3 units

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
