Answer 1

Step-by-step explanation:

area of rectangle = l×b

20 = 5×l

4= l

therefore, height of triangle = 4

area of triangle = 1/2× base×height

=1/2×5×4

=10cm²

Answer 2

Answer:

10cm^2

Step-by-step explanation:

area of triangle =length ×breadth

in ques they gave length of rectangle and area of rectangle

so , 20=l×b

5×b

b=20/5

=4cm

now in question it is given that height of triangle is equal to height of rectangle which means the breadth which we found as 4 cm

now area of triangle =1/2×b×h

=1/2×5×4

=10cm^2
