Step-by-step explanation:
there is a rectangle and an octagon within
area of rectangle = 8*9 = 72
there are 4 right angled triangles
area of one such triangle = .5 × 9 = 4.5
total area of triangles = 18
area of octagon = 72-18 = 54 m^2
Answer:98%
Step-by-step explanation:
Answer is -7/2
Gradient or slope is found by change in y over change in x.
Or
(y2 - y1) over (x2 - x1)
So
(-2 -5) over (4-2)
= -7/2
Pairs of angles made by intersecting lines.
Answer:
56 in
Step-by-step explanation:
Square ....so each side is = x
x * x = area = 196
x^2 = 196
x = sqrt (196) = 14 in
perimeter = x + x + x + x = 56 in
