Question

In the figure DH perpendicular on
Side Ef Cand seg gk perpendicular on
Side EF If GK = 200m
and A(∆DEF) = 300cm²
find 1. EF​

Answer 1

Answer:

seg DH ⊥ side EF

seg GK ⊥ side EF

DH = 12 cm

GK = 20 cm

A (Δ DEF) = 300 cm ²

To find:

(i) EF

(ii) A (ΔGEF)

(iii) A (⎕ DEGF)

Solution:

(i) Finding EF:

In Δ DEF, we have

EF = base

DH = height = 12 cm

Area (Δ DEF) = 300 cm²
