Work out the base of a square with area 225cm²

15cm

Step-by-step explanation:

Given parameters:

Area of the square = 225cm²

Unknown:

Base  = ?

Solution:

A square is a figure with equal sides.

Area of a square  = L²

L is the side length

    225cm²  = L²

       L = √225

       L = 15cm

The base of the square is 15cm

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
