7 cm.
Q. 2 Find out the area of a triangle with base 25 cm and a Perpendicular from apex
length is of 1.5 cm.
Q. 3. Find out the perpendicular (apex) length of a triangle where base is 6.5 cm and
the area is 26 cm.
Q. 4. Find out the area of a triangle where base is 120 dm and height is 75 dm.​

Answer 1

Step-by-step explanation:

1. Solution :

Area of a triangle = 12b×h

Here , b = 12 cm and h = 8 cm

∴ Required area = 12×12×8=48cm2

2. -

3. Therefore, The perpendicular height of the triangle is 8 cm.
