The area of the parallelogram using area of rectangle and area of two triangles is 84 m²
<h3>How to find area of a parallelogram</h3>
- Area of a rectangle = length × width
= 8m × 7m
= 56 m²
- Area of each triangle = 1/2 × base × height
= 1/2 × 4m × 7m
= 1/2 × 28
= 14m²
- Total area of triangles = 2(14 m²)
= 28 m²
- Area of parallelogram = area of rectangle + area of two triangles
= 56 m² + 28 m²
= 84 m²

Answer:
BC= 1.92837
Step-by-step explanation:
sin40=0.64279
or,perpendicular(BC)<em>/</em>hypotenuse(AB)=0.64279
or,BC/AB=0.64279
or,BC/3=0.64279
or,BC=0.64279 x 3
:.BC=1.92837 <u>ans</u>
