11. what is the altitude of a rhombus if its area is 10 square meters and the length on one side is 2.5 meters? a. 4 m b. 10 m c. 7.5 m d. 12.5 m

4 m so, A.

Step-by-step explanation:

Area = side x altitude then,

Your altitude = area/side

which =40/12.5= 4 m  

Hope my answer has helped you!

A. 4 m

Step-by-step explanation:

We know that a rhombus is a kind of parallelogram.

Area of parallelogram = (Altitude ) x ( Base)

Thus , Area of rhombus = (Altitude ) x ( Base)

As per given , Base =  2.5 meters

Area of rhombus = 10 square meters

Substitute all values in formula , we get

Hence, the altitude of a rhombus is 4 m.

Thus , the correct answer is A. 4 m ,

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
