Each unit on the coordinate grid represents 1 yard. the rectangular pool and triangular hot tub shown are both in need of covers. how much total material is needed to cover both? square yardsplz give details, i don't understand the concept of this problem!

Vertices of rectangular pool are A(3,2),B(7,8),C (4,10), and D (0,4).

AB= yard=CD

BC= yard=DA

Area of rectangular pool=Length × Breadth

                                         =√52 ×√13=13×2=26 square yard

Vertices of triangle are P(5,2),Q(7,2) and R(7,5).

PQ= 2 units, QR= 3 units

Area of right triangle PQR= ×PQ×PR

                                            =×2×3= 3 square yards

Total material needed to cover bot rectangular pool and triangular hot tub= Area of rectangle + Area of right triangle=26+3=29 square yards
