Answer:
The other diagonal measures 21m
Step-by-step explanation:
In this question, we are tasked with calculating the length of the second diagonal of as Rhombus given the measure of the surface area of the rhombus and the length of the other diagonal
Mathematically, for a rhombus having two diagonals and
, the area of the rhombus can be calculated mathematically using the formula below;
A = 1/2 × ×
From the question, we can identify that A = 157.5 and
= 15m
we input these in the formula;
157.5 = 1/2 × 15 ×
315 = 15
= 315/15
= 21m
