the length of one side of a parallelogram is two over three times the length of its adjacent side if perimeter of the parallelogram is 20 cm find the sides of the parallelogram

Step-by-step explanation:

Let the two sides be A and B, such that:

Required

Find A and B

The perimeter is calculated as:

Substitute for A and 20 for Perimeter

Divide both sides by 2

Multiply both sides by 3

Solve for B

Recall that:

Hence, the lengths of the sides are 4 cm and 6 cm

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
