Question

Find the altitude of the rhombus whose area is 315 cm² and its perimeter is 180 cm

Answer 1

Answer:

Perimeter of rhombus = 180 cm

Length of side = 180/4 = 45 cm

Area of rhombus = 315 = bh = 45h

h = 315/45 = 7 cm.

Step-by-step explanation:

Answer 2

Answer:

Altitude = 7cm

Step-by-step explanation:

In order to find the altitude we need to find the base....

Base of the rhombus = $\frac{180}{2}$

                                   = 45cm

Area of Rhombus = Base x Height/Altitude

315cm² = 45cm x altitude

$\frac{315}{45}$ = Altitude

Therefore, 7cm = Altitude
