I'm stuck on how to find the area of these problems. Any help?

Step-by-step explanation:

For the rectangle, the area equation is just length x width. It's just multiplying exponents, too. So just multiply (4x^5)(0.25x^2) and when multiplying exponents, you add them. So you would get x^7

For the triangle, bh/2

Multiply (1.5x^9h^6z)(6x^5h^3z^6)

add exponents of like terms

I got (9x^14)(y^9)(z^7)/2

Also in word form it's nine x to the 14th, y to the ninth and z to the 7th. Divide by two and you divide 9/2 and keep that number with the exponents.

I got 4.5x^14y^9z^7, anyone else? Idk I'm in ap calc and i should be able to do this. if it doesn't work this way, try the FOIL method.
