Answer 1

(1)
Ar of $△$PQA = $\frac{1}{2}\times \mathrm{QA}\times \mathrm{PA}=\frac{1}{2}\times 30\times 50=750$ ${\mathrm{m}}^2$
Ar of $△$PBT = $\frac{1}{2}\times \mathrm{PB}\times \mathrm{BT}$ = $\frac{1}{2}\times 60\times 30=900{\mathrm{m}}^2$
Ar of $△$SBT = $\frac{1}{2}\times \mathrm{SB}\times \mathrm{BT}=\frac{1}{2}\times 90\times 30=1350{\mathrm{m}}^2$
Ar of $△$RCS = $\frac{1}{2}\times \mathrm{RC}\times \mathrm{CS}=\frac{1}{2}\times 25\times 60=750{\mathrm{m}}^2$
Ar of QRCA = $\frac{1}{2}\left(\mathrm{QA}+\mathrm{RC}\right)\times \mathrm{AC}=\frac{1}{2}\times \left(50+25\right)\times 60=2250$ m²
Ar os PQRST = Ar of $△$PQA + Ar of $△$PBT + Ar of $△$SBT + Ar of $△$RCS + Ar of QRCA
= 750 + 900 + 1350 + 750 + 2250
= 6000 m²
