Question

Work out the area of the triangle pls help

Answer 1

Answer:

answer area of triangle is 84m^2

GIVEN:-

SIDES =17m,10m,21m

21m is the base

ALTITUDE= 8m

→AREA OF TRIANGLE=$\frac{1}{2}$×Base×height

on substituting the values we get,

=$\frac{1}{2}$×21m×8m

=$\frac{1}{2}$×168$m^{2}$

on cancelling we get,

=84$m^{2}$

THEREFORE AREA OF THE TRIANGLE IS 84$m^{2}$

ADDITIONAL INFORMATION:-

AREA OF TRIANGLE=$\frac{1}{2}$×base×height

AREA OF RECTANGLE=length×breadth

AREA OF SQUARE=side×side

AREA OF RHOMBUS=$\frac{1}{2}$×$d_{1}$×$d_{2}$

AREA OF PARALLELOGRAM=base×height

AREA OF CIRCLE=$\pi r^{2}$

AREA OF SEMICIRCLE=$\frac{\pi r^{2} }{2}$
