Question

1. If the area of a
right angled
triangle is 240 sq
meters & base is
30 m. find the
perimeter of the
triangle.​

Answer 1

Answer:

Perimeter of the triangle is 80m

Step-by-step explanation:

Area of triangle = 240 m²

Base = 30m

Height = h(let)

Area of triangle 1/2 * Base * Height

240 m² = 1/2 * 30m * h

h = 16m

perimeter = Sum of all sides

we have base, perpendicular height

so we have to find hypotenuse

By Pythagoras theorem,

H² = P² + B²

H² = 16*16 + 30*30

So hypotenuse is 34m

Perimeter of triangle is 34m + 30m + 16m

80m

Answer 2

Area of a right angle is = 240m

base of a right angle is=30m

Perimeter of triangle = side+side+side

= 30+30+30= 240

=. 90

BREADTH=90
