1. A field in the form of a parallelogram has one diagonal of 42 m long and the perpendicular
distance of this diagonal from either of the
outlying vertices is 10 m as shown in the figure.
Find the area of the field.

420m²

Step-by-step explanation:

Given that:

Length of diagonal = 42m

Lenght of outlying vertice = 10 m

Area of paralellogram = 2 " (area of triangle)

Area of triangle = 1/2 * base * height

Hence,

Area of parallelogram :

Area = 2(0.5 * 42 * 10)

Area = 2 (210)

Area = 420m²

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
