A square had a perimeter of 28 ft. What is its area?

2 answers:

7 0

You will find the side by 28 ÷ 4 = 7 ft because a square has 4 equal sides.
Then we will do side × side to find the area of a square, so 7 × 7 = 49 ft²
So the answer is 49ft²

Describe and correct any error a student may have made when solving the equation

Lady_Fox [76]

Answer:

The student made an error during the distributive property in the second step where they multiplied 0.15 by -0.2 to equal -0.3 when it should have been -0.03.

Step-by-step explanation:

$0.15(y-0.2)=2-0.5(1-y)\\0.15y-0.03=2-0.5+0.5y\\0.15y-0.03=1.5+0.5y\\100(0.15y-0.03)=100(1.5+0.5y)\\15y-3=150+50y\\15y-3-15y-150=150+50y-15y-150\\-153=35y\\-\frac{153}{35}=y$
