Can someone me with this maths question. asap

Since we are given the perimeter, we add the lengths of the sides and set the sum equal to the perimeter. Then we solve for x.

3x + 3x - 1 + 4x + 1 = 70

10x = 70

x = 7

Now we pick two sides that can be used as a base and a height to calculate the area. In a right triangle, the legs form a right angle, and can be used as base and height.

base = 3x = 3(7) = 21

height = 3x - 1 = 3(7) - 1 = 21 - 1 = 20

area = base * height/2

area = (21)(20)/2 = 21 * 10 = 210

210

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
