Answer 1

$\huge\underline\red{AnSweR}$

Side of rectangle is = 3.5 cm and 4.5

Area of rectangle is =L×B

=(3.5×4.5 cm)

=15.75 cm

Answer is = 15.75 cm.....

Answer 2

Answer:

Area of rectangle is = Length * Breadth ....

Area of rectangle is = Length * Breadth ....= 3.5 * 4.5 = 15.75...

area of triangle = a^2 + b^2 = c^2

= 3.5 ^2 + 4.5^2

= 12.25 + 20.25

c^2 = 32. 50

Thus area of triangle is 32.5cm
