Question

given rt=14.3 and su=43, find the area of rhombus rstu. round your answer to the nearest tenth if necessary.

Explanation:

Step1: Recall area formula for rhombus

Area = $\frac{1}{2} \times d_1 \times d_2$ where $d_1,d_2$ are diagonals.

Step2: Identify diagonals

$d_1=RT=14.3$, $d_2=SU=43$

Step3: Calculate area

Area = $\frac{1}{2} \times 14.3 \times 43 = 0.5 \times 14.3 \times 43 = 308.45$

Step4: Round to nearest tenth

308.45 ≈ 308.4

Answer:

308.4
