# Find the Areas of Given Plots. (All Measures Are in Metres.) - SSC (English Medium) Class 8 - Mathematics

ConceptArea of a Triangle by Heron’S Formula

#### Question

Find the areas of given plot. (All measures are in metres.)

#### Solution

Ar of Δ PQA = 1/2 xx QA x PA = 1/2 xx 30 xx 50 = 750 m²

Ar of Δ PBT = 1/2 xx PB x BT = 1/2 xx 60 xx 30 = 900 m²

Ar of Δ SBT = 1/2 xx SB x BT = 1/2 xx 90 30 = 1350 m²

Ar of Δ RCS = 1/2 xx RC x CS = 1/2 xx 25 xx 60 = 750 m²

Ar of QRCA = 1/2 (QA + RC) x AC = `1/2 xx (50 + 25) x 60 = 2250 m²

Ar os PQRST = Ar of Δ PQA + Ar of Δ PBT + Ar of Δ SBT + Ar of Δ RCS + Ar of QRCA.

= 750 + 900 + 1350 + 750 + 2250

= 6000 m²
