Base of a triangle is 6 and height is 4. Base of another triangle is 5 and height is 3. Find the ratio of areas of these triangles
Answers
Here's your answer.. ⬇⬇
♦ Given :- Let The triangle be ∆ABC and ∆PQR.
In ∆ABC,
Base of ∆ABC is BC = 9cm
Altitude of ∆ABC is AE = 5cm
In ∆PQR,
Base is QR = 10cm
Altitude is PM = 6cm
♦ To Find :- Ratio of Area of ∆ABC and ∆PQR
♦ Solution :-
\begin{gathered} = \frac{area \: \: of \: \: abc}{area \: \: of \: \: pqr} \\ \\ = \frac{ \frac{1}{2} \times ae \times bc }{ \frac{1}{2} \times pm \times qr } \\ \\ = \frac{ \frac{1}{2} \times 5 \times 9 }{ \frac{1}{2} \times 6 \times 10} \\ \\ = \frac{3}{4} \\ \\ \end{gathered}

And if numbers are not same just follow the process you will get your answer :)
Let the first triangle be ∆ABC
Let the second triangle be ∆DEF
In ∆ABC :-
Base b = 6; Height h = 4
Area A = ½ × b × h
A = ½ × 6 × 4
A = 1 × 3 × 4
A = 12
In ∆DEF :-
Base b = 5; Height h = 3
Area A = ½ × 5 × 3
A = 15/2
Ratio of Area of ∆ABC : Area of ∆DEF :-
Area of ∆ABC : Area of ∆DEF
12 : 15/2
8 : 5
