Solution
The ratio of the areas of two triangle with common base A1:A2=8:7 Height of the larger triangle (h1)=4cm Height of the smaller triangle (h2)=?
Area of larger triangleArea of smaller triangle=b1×h1b2×h2
87=4h2
h2=7×48cm
=3.5cm
Hence, the corresponding height of the smaller triangle is 3.5cm.
