Answer 1

Step-by-step explanation:

672 is the answer for above question

thanks I gained ACE just now for this question

Answer 2

Answer:

We know that all the angles of a rectangle are 90° and the diagonal divides the rectangle into two right angled triangles.

So, 48 m will be one side of the triangle and the diagonal, which is 50 m, will be the hypotenuse.

According to the Pythagoras theorem:

(Hypotenuse)² = (Base)² + (Perpendicular)²

Perpendicular = √(Hypotenuse)²-(Base)²

Perpendicular = √(50)²-(48)²=√2500-2304=√196=14 m

∴ Other side of the rectangular plot = 14 m

Length = 48m

Breadth = 14m

∴ Area of the rectangular plot = 48 m × 14 m = 672 m²

Hence, the area of a rectangular plot is 672 m²
