5.Find the altitude of a parallelogram whose area is 2.25m² and base is 250cm. |
| Answer» EXPLANATION:The FORMULA for the area of a square is:A=s2 Where:A is the area of the square.s is the length of the side of a square.Substituting and SOLVING for s gives:225 cm2=s2 We can TAKE the square root of each side of the equation giving:√225 cm2=√s2 15 cm=s s=15 cm The formula for the perimeter of a square is:p=4s Where:p is the perimeter of the square.s is the length of the side of a square.Substituting for s from the solution for the previous formula and calculating p gives:p=4×15 cm p=60 cm | |
