Answer:
Area of shape = 187 cm²
Step-by-step explanation:
Given:
Length of rectangle = 15 cm
Width of rectangle = 9 cm
Height of triangle = (22-9) cm = 13 cm
Base of triangle = (15-7) cm = 8 cm
Find:
Area of shape
Computation:
Area of shape = Area of rectangle + Area of triangle
Area of shape = (l)(b) + (1/2)(b)(h)
Area of shape = (15)(9) + (1/2)(8)(13)
Area of shape = 135 + 52
Area of shape = 187 cm²
You will need to subtract 28 from 15 and you will get 13. so you answer is 13
Step-by-step explanation:
In right angled triangle ABC,
Taking alpha as reference angle,
By pythagoras theorem,
p=BC,h=AB,b=AC
Taking thita as reference angle,
p=AC,h=AB,b=BC

A=(a(b))/2
surface area and area are the same in 2D shapes
A= (1.5(1.2))/2 =(1.8)/2 = 0.9 m squared
The line of symmetry.
It divides the parabola into to halves that are exactly the same.
