Question

. The height of a triangle is equal to
the perimeter of a square whose
diagonal is 9√2 m and the base of the
same triangle is equal to the side of the
square whose area is 784 m2. What is
the area (in m2) of the triangle?​

Answer 1

Answer:

Height of triangle = perimeter of square

Diagonal of square = 82–√

m

∴ Length of each side of square :

=82–√2–√=8m

∴ Perimeter of square = 4 × 8 = 32 m = Height

Area of other square = 729

Side of square = 729−−−√

= 27 m = base of triangle

∴ Area of triangle :

=12×Base×Height=12×27×32=432 sq.metre
