Question

ASAP PLS Answer TY!!! On the coordinate plane shown, each grid unit represents 10 feet. Polygon QRST has vertices Q(10, 30), R(−20, 30), S(−20, −10), and T(10, −10), and represents the floor plan of a room. Find the perimeter and area of the room

Answer 1

P= 140 ft

A= 1200 sq ft

Explanation:

ST = RQ = 30

QT = RS = 40

P= (30 × 2) + (40 × 2) = 140 ft

A= 40 x 30 = 1200 sq ft
