The height of a parallelogram is 3 times the base. the base measures 4.5 cm
what is the area of the parallelogram?

The area is 60.75 cm²

Step-by-step explanation:

Let h = 3b (height is 3 times the base)

Since the base is 4.5 cm, the height is 3(4.5 cm) = 13.5 cm.

The area of a parallelogram is A = L·H, which here is:

A = (4.5 cm)(13.5 cm) = 60.75 cm²

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
