♧♧Answered by Rohith kumar maths dude :-

♧♧Given: -

  • Ratios of areas of two triangles with equal heights is 2:3.

♧♧To prove:-

  • corresponding base of bigger triangle

♧♧Proof:-

♧Let M1 and M2 be the areas of two triangles .

♧And N1 and N2 be their corresponding bases.

M:M= 2:3

♧♧Therefore,

M1/ M2 = 2/3

  • M1/M2=N1/N2 (are have equal heights )

2/3=6/N2

b2= (6×3)/2

b2=9cm.

♧♧Hence, the corresponding sides of bigger triangle is 9cm.

♧♧Hope it helps u mate .

♧♧Thank you .

Answer:

Let us assumed that,

Area of bigger triangle =  \sf \: A_1 =  \frac{1}{2}  \times h \times BC

Area of smaller triangle =  \sf \: A_2 =  \frac{1}{2}  \times h \times EF

Base of smaller triangle = EF = 6 cm

Base of bigger triangle = BC = to find

So according to the question,

Given,

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \: A_1 : A_2  = 2 :3 \\   \implies\sf \:  \frac{A_1}{A_2}  =  \frac{2}{3}  \:  \:  \:  \:   \\\implies\sf \: \frac{\frac{1}{2}  \times h \times BC}{  \frac{1}{2}  \times h \times EF}   =  \frac{2}{3}  \\ \implies\sf \: \frac{BC}{EF}  =  \frac{2}{3}  \\ \implies\sf \: \frac{BC}{6}  =  \frac{2}{3}  \\ \implies\sf \:BC =  \frac{2  \times 6}{3}  \\ \implies\sf \:BC = 4 \: cm

So base of bigger triangle BC = 4 cm
