Answer:

Therefore the area of the quadrilateral =35 cm²

Step-by-step explanation:

Given, the length of one of diagonal of quadrilateral is 10 cm and perpendicular drawn from the opposite vertices to this diagonal are the length of 2.8 cm and 4.2 cm.

A diagonal divided a quadrilateral into two triangle.

Therefore the area of the quadrilateral

= sum of the area of the triangles

=(\frac{1}{2}\times 10\times 2.8+ \frac{1}{2}\times 10\times 4.2)cm²      [ area of a triangle= \frac{1}{2}\times base\times height]

=35 cm²

Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds. Who was moving faste
Andrews [41]

Answer:

Mai was moving faster.

As, she covered a greater distance in the same amount of time.

Step-by-step explanation:

Given: Mai traveled 15 meters in 6 seconds and Priya travels 22 meters in 10 second.

Calculate the speed of both;

Speed defined as the rate at which an object covers distance.

Speed = \frac{Distance}{Time}

Mai traveled 15 meters in 6 seconds

then;

Speed = \frac{15}{6} = 2.5 m/s

Priya travels 22 meters in 10 second.

then;

Speed = \frac{22}{10} = 2.2 m/s

Reason: Mai traveled faster because she covered a greater distance in the same amount of time.
