Question

A sign is in the shape of a rhombus. The diagonals are 1.75 feet and 2.5 feet. What is the area of the sign? 2.125 ft2 2.1875 ft2 4.25 ft2 4.375 ft2

Answer 1

Area = 2.1875

Explanation:

The formula for area of a rhombus is A = 1/2(d1)(d2), where d1 is one of its rhombus and d2 is the other. Thus, to find the area, we can plug into the formula 1.75 for d1 and 2.5 for d2 and solve for A:

A = 1/2(1.75)(2.5)

A = 0.875*2.5

A = 2.1875
