Answer:
approx answer should be 25
Explanation:
you should have given naming to figure
but let it be
so coming to the answer
length of base of the triangel will be half the length of base of rectangle by symmetry so base length of triangle = 7/2
to find perimeter we have to do sum of lengths of all sides
so by pythagoras theorem we can find side length of triangle
(7/2)^2 + 2^2 = side^2
side = 4.04 approx so let take side = 4 for easy calculation
now triangel is equilateral so other side is also same now we have to just do just sum of all sides
= 5+5+7+4+4 = 25 approx answer should be 25
if you take side length of triangle as 4.04 you will get accurate answer
hope this answer help
