The area of a triangle, whose base and corresponding altitude are 6cm and 5cm, is equal to the area of a right triangle whose one of the side containing the right angle is 2.5 cm. find the other side of the triangle.
Answers
Answer:
The other side of the triangle is 12 cm.
Step-by-step explanation:
✅Area of triangle = ½ base × height
✔️Area of triangle 1 = ½ × 6 × 5
✔️Area of triangle 1 = 15 cm²
✅Area of ∆ 1 = area of right angled ∆ .
15 cm² = area of right angled ∆ .
Area of right angled ∆ = ½ ×product of
sides containing
the rt. angle
✔️½ × 2.5 cm x b = 15 cm²
✔️2.5 × b = 30 cm
✔️b = 12 cm
Hence the other side of the triangle is 12 cm.

Answer:
AREA OF TRIANGLE 1
Area of triangle = base×altitude/2.
=(6)×(5)/2.
=30/2.
=15 sq.cm. .
BOTH TRIANGLES HAVE SAME AREA= 15sq.cm.
also, area of right triangle =base×height/2
=15=b×2.5/2
=15×2/2.5=b
=30×10/25=b
=12=base
therefore,base and other side of triangle =12 cm
things to remember:
- attitude is also known as height
- area of right triangle is base × height/2
