Question

Please Tell this answer.

Answer 1

Step-by-step explanation:

Area of ∆ = 1/2 × height × base

so,

we know

height = 7 cm

base = 6 cm

so, after inserting the values we got

→ 1/2 × 7 × 6

→ 7 × 3 = 21 cm²

so,

a) Area of ∆ABC = 21cm²

and also,

Area of ∆ABC = 1/2 × AC × BQ

so, after inserting the values we got,

→ 21 = 1/2 × 10 × BQ

→ 21 = 1 × 5 × BQ

→ BQ = 21/5 = 4.2

so ,

b) BQ = 4.2 cm

hope this answer helps you dear!
