Question

can someone help me in this??

Answer 1

Answer:

Area of a rectangle is 6 times the area of a small rectangle

Area of a rectangle is 6 times the area of a small rectangleLength of both the rectangles are equal

Answer 2

first,

area of triangle =

$\frac{1}{2} \times base \times height$

=

$\frac{1}{2} \times 12 \times 10$

=

$\frac{120}{2}$

= 60cm²

according to the question,

area of rectangle = 6(area of triangle)

= 6(60)

= 360cm²

we know that,

area of rectangle =

$breadth \: \times length$

=

$x \: \times 40 = 360$

$x \: = \frac{360}{40}$

$x = 90$

hence breadth is 90cm.

hope it helps

have a great day
