Question

Can someone solve this for me please.

Answer 1

• The value of PR is 21 ft.

Explanation:

We know that:

• 3(PQ + QT + TP) = PR + RS + SP
• PQ = 7 ft.
• QT = 4 ft
• RS = 12 ft.

Work:

• 3(PQ + QT + TP) = PR + RS + SP
• => 3(7 + 4 + TP) = PR + 12 + SP
• => 21 + 12 + 3TP = PR + 12 + SP
• => 21 + 3TP = PR + SP
• => 21 + SP = PR + SP [3TP = SP]
• => 21 = PR

Hence, the value of PR is 21 ft.

Hoped this helped.
